box.space._ck_constraint
_ck_constraint is a system space where check constraints are stored.
Tuples in this space contain the following fields:
- the numeric id of the space ("space_id"),
- the name,
- whether the check is deferred ("is_deferred"),
- the language of the expression, such as 'SQL',
- the expression ("code")
Example:
tarantool> box.space._ck_constraint:select()---- - [527, 'c1', false, 'SQL', '"f2" > ''A''']- [527, 'c2', false, 'SQL', '"f2" == UPPER("f3") AND NOT "f2" LIKE ''__''']...
